IM PROVEM ENT IN SASH-FASTENERS.

Specification forming part of Letters Patent No. 210,053, dated November 19, 1878 application filed October 10, 1878.

Look, of which the following is a specification Figure 1 is a front view of a window to which our improvements have been applied. Fig. 2 is a vertical section of the same, taken through the line .10 m, Fig. 1. Fig. 3 is a (letail vertical section taken through the line y y, Fig. 2. Fig. 4 is a detail view of the same, the stop being removed and the clampingscrews being shown in section.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved stop, fastener, and lock for windows which shall be so constructed that it may be easily and quickly adjusted to allow the sash to work freely when swollen and when shrunken, which will hold the sash securely in any position into which it may be raised, which will lock the sash securely when fully lowered, and which at the same time shall be simple in construction, easily applied to a window, and

convenient and reliable in use.

The invention consists in the combination of the clamping-screws, the slotted plates, and the sliding nuts with the stop and the frame of a window; and in the combination of the sliding slot-ted and notched bar, the spring, and a screw or pin with the stop, the frame, and the sash of a window, as hereinafter fully described.

A represents the frame of a window; 13, the lower sash; C, the upper sash, and D the stops. E are the clamping-screws, which pass in through holes in the stop D, through slots in the plates F, and screw into the nuts G. The plates F are secured in countersunk recesses in the frame A, and are slotted transversely for the passage of the screws E.

be desired.

Two or-more sets of the screws, plates, and. nuts E F G may be used, as the length of the stops D may require.

With this construction, by loosening the screws E the stops D may be moved out or in, as the sash B maybe swollen or shrunken, and by tightening the said screws E the said stops D will again be firmly secured in place, so that all rattling or jamming of the sash may be prevented. In the inner side of the stop D is formed a transverse groove, in which is placed a cross-bar, H, which is slotted longiti'idinally to receive a screw, E, or a pin, by which its movements are limited.

Upon the projecting outer end of the bar H is formed, or to it is attached, a shoulder, knob, or other handle, for convenience in drawing it outward for releasing the sash. In the lower edge of the projecting outer part of the bar H is formed a notch to receive the upper end of the spring I, the other end of which is attached to the outer edge of the stop D, and, which is so formed as to press the said bar H. inward. The inner end of the bar 11 rests against the forward side of the side rail of the sash B with sufficient pressure to hold the said sash securely in any position into which it may be adjusted. The bar 11 is secured to the stop D insuch a position that the inner end of the said bar, or a tenon formed upon the said end, may rest, when the sash B is fully lowered, upon the upper edge of the said sash B, and thus prevent the said sash from being raised until the said bar 11 has been drawn outward.

Having thusdescribed our invention, we claim as new and desire to secure by Letters Patent- 1. The combination of the clainpingscrews E, the slotted plates F, and the sliding nuts G with the stop D and the frame A of a win dow, substantially as herein shown and described.

2. The combination of the sliding, slotted, and notched bar H, the spring I, and a screw or pin, E, with the stop D, the frame A, and the sash B of a window, substantially as here in shown and described.
